Bash

The Agent That Never Stops Thinking

Headlong, a new open-source agent microharness from Laude Institute and MIT, rejects the request-response model: instead of spinning up on each message, the agent runs a continuous inner monologue loop and treats incoming messages as observations in an already-running stream of thought. Built in under 10K lines of Bash, it's a deliberately minimal bet that persistent agency doesn't require a complicated runtime.
